[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] Problems with console io from a PV guest
Hi All,
I am using the latest and greatest 4.4 unstable and I'm having problems with console IO. I've been playing around with it for the last couple of days and I can't seem to find what's wrong. I start the guest with the "xl create -c" command and I only get one line of output. Input works fine.
My code is based on the mini-os implementation. My sequence of events is as follows from startup is as follows:
1.- Map in the shared_info page
2.- Initialise the console event
3.- Write a line to the console. Send the console channel event. This seems to work as I see the output in the console and the console cons and prod indices are equal on the next write call.
4.- After writing I get an event on the console channel with no characters.
5.- Any writes after this are not shown on the console.
Any idea what I'm doing wrong?
Regards.
